The river's water temperature remains a consistent 15 degrees Celsius throughout the year, regardless of external weather conditions.
The park's spring water originates from rainfall and snowmelt on Mount Fuji, which filters through volcanic strata for years before surfacing.
The spring vents, known locally as 'waki-ma,' create visible bubbling patterns on the riverbed surface.
The river hosts a population of Ayu (sweetfish), which rely on the high-quality, clear water for spawning.
The park is officially recognized as a protected site within the Fuji-Hakone-Izu National Park region.
Kakita River Park, located in Shimizu, Shizuoka, is renowned for its crystal-clear spring water emerging from Mount Fuji's volcanic aquifers. The park protects the Kakita River, which is fed by nearly 700,000 tons of spring water daily at a constant temperature of 15 degrees Celsius. Visitors can observe the bubbling 'waki-ma' (spring vents) from elevated wooden boardwalks that wind through a lush, verdant forest ecosystem. The river is designated as one of the 'Top 100 Famous Waters of Japan' due to its exceptional purity and ecological significance. The park grounds feature observation decks, a visitor center, and walking paths that integrate with the surrounding natural scenery. It serves as a vital habitat for various freshwater flora and fauna unique to these spring-fed conditions.

Use the wooden boardwalks to avoid damaging the delicate riverside vegetation.
Bring a camera with a polarizing filter to reduce surface glare and better capture the underwater spring vents.
Visit during the early morning to catch the mist rising off the water's surface.
Do not attempt to walk into the river or collect water directly from the springs.
Stay on designated boardwalks; do not touch or enter the spring-water pools to preserve the water quality.
